Clamxir Build Status

ClamAV wrapper for elixir based on clamby

This package depends of clamav installed on your system. Please refer to: https://www.clamav.net/documents/installing-clamav.

As recomendation, use the daemonize flag on the configs, in order to improve performance.

Installation

The package can be installed by adding clamxir to your list of dependencies in mix.exs:

def deps do
  [
    {:clamxir, "~> 0.1.8"}
  ]
end

Usage

Clamxir receive the configs on each public method, and based on the configs, will perform their task.

The config file by default is the struct %Clamxir{}. The default values of the structure are:

%Clamxir{
  daemonize: false,
  stream: false,
  check: fase
}

daemonize is a flag to use one instance of the clamav instead of the creation of new instances for each request.

iex> Clamxir.safe?(%Clamxir{}, "/path/file")

stream will pass the argument --stream to clamdscan, this will help to avoid permission issues.

iex> Clamxir.safe?(%Clamxir{stream: true}, "/path/file")

check flag will add validation of the scanner availability before try to run it.

iex> Clamxir.safe?(%Clamxir{check: true}, "/path/file")

Integration with Phoenix

  1. Install as dependency mix.exs
{:clamxir, "~> 0.1.8"}
  1. Use in the controller action where the files are uploaded
def upload(conn, params) do
  file = params["index"]["file"]
  # Requires to have clamavdscann to work
  case Clamxir.safe?(%Clamxir{daemonize: true}, file.path) do
    true ->
      # Process the file and ...
      conn
      |> put_flash(:info,  "Created successfully")
      |> redirect(to: "/")
    false -> conn
      |> put_flash(:error,  "Virus!!")
     |> redirect(to: "/")
  end
end
